Abstract
Methods, systems and storage media are described, each of which may be used to generate an image of an object using ultrasonic plane waves. For example, the generated image may be of a target object positioned on a platen surface. The image may be derived from corrected output signals obtained from a plurality of selected sensor pixels. The corrected output signals may adjust for diffraction of reflected ultrasonic plane waves from a target object positioned on the platen surface. The target object may be a finger or a tip of a stylus.
